The song seems best suited to a relationship between two humans, but I suppose one could also relate it quite easily to the relationship between a man and his God.
As was already said, this song was written about his wife, it's about his wholehearted dedication no matter how miserable it makes him, that he would willingly decay with her.
If one were to relate this to one's relationship with God, one could see how a man could attempt to be so dedicated to God that he would actively pursue Him regardless of what suffering or misery he may encounter as a result. Becoming so dependant that he dreads the concept that he may ever be distant from God.
